Hi,

This is to announce a set of Makefile's that aim to build every STM32 Library under Linux using GCC. Comments are welcome.

Please see

Cheers,

Rick

Hi,

your aim is a noble effort! However, gnu makefiles are a pain to maintain and extend beyod a small project (I speak from experience).

A better alternative is CMake. I've successfully used CMAke for building STM32 firmware on FreeBSD for many years.

[small excerpt from CMake output for STM32L0] :

CMake is fantastic and very easy to configure.

If you need tips about it ask around!

In general I agree. I've struggled with makefiles myself. But in this instance the makefiles are very simple and tiny. The issues here are more about fixing up the wrong case issues (I guess the library assumes it's being built in MSDOS), inconsistency in directory structure names across different chip families and tweaking of loader scripts. Don't think cmake will help with those issues. Appreciate your input.
